The Contract Works can generally be summarised as the following: Installation of approximately 60m of DN300 & DN225 PVC-U stormwater piping and related structures to renew the existing above ground piping that runs along and over the heritage concrete stormwater channel running alongside the boundary of 14 St David Street between St David Street and The Terrace in Lyttleton.

The work involves the removal of the existing DN200 above ground concrete piping and reinstatement of a new stormwater above ground piping on plinth structures to protect the integrity of the heritage channel.
